ZJ Series Centrifugal Slurry Pump
Product Description
As one of the earliest centrifugal slurry pump manufacturers, our ZJ series slurry pump has a single-stage and centrifugal-type suction design. The wet part is composed of high chrome white iron and possesses anti-abrasive, anti-shock properties, which optimize performance, extend the life of the wetted parts of pumps, and increase cost-effectiveness. The discharge diameter of the horizontal model ranges between 650mm-40mm. The heads may be customized by selecting different impellers to suit your purpose, or the impeller installed may be cut to your specifications.
Our pump designs are not only constructed to withstand shocks, but also high pressures. These models are ideal for multi-stage operations, such as long tailings disposal pipelines. Here, the pumps are constructed with a split casing and light replaceable liners, and the strength is provided by the two halves of the casing being bolted together. The liners are held in position by the housing, which accommodates all internal and external loads.
Product Features
Main Application
- Double liners metal structure
- Vertical middle split casing
- Re-positional discharge port- 8 different positions at 45-degree angles
- Variable bearing lubrication options, depending on the design of bearing housing.
- Thin-oil lubrication may be used for box type
- Grease lubrication may be used for cylinder type
- Thin-oil or grease lubrication may be used for bearing housings with an inserted cover.
This type of centrifugal slurry pump can be used in series or in parallel and is widely applied in power plants, metallurgy, coal washing, building, chemical industries, and press filter pump systems. Typical applications include the transport of abrasive slurries such as those found in the concentrate and tail slurry of ore dressing plants, slag handling in power plants, coal mud transport, medium to heavy coal separation, sand transport in shore-based operations, and feeding filter presses. The maximum weight concentration of slurry that can be processed varies with the type, approximately 45% for mortar slurry and 65% for mining slurry. This model can be driven by DC, V-belt, hydraulic coupling, or frequency-speed-adjusting transmission types.
